SKion acquires significant parts of the BMZ Group, manufacturer of lithium-ion battery systems
Bad Homburg, 19 December 2025 – SKion GmbH (“SKion”) has today entered into a binding agreement to acquire significant business units from the self-administration proceedings of BMZ Holding GmbH and BMZ Germany GmbH, Karlstein am Main (“BMZ Group”). The acquisition is subject to approval by the antitrust authorities.
Previously, SKion has been a minority shareholder of the BMZ Group. Since the beginning of the proceedings, SKion has supported the company and provided bridge financing to ensure the continuation of its operational business. As part of a structured bidding process, potential investors were sought for an acquisition. On this Friday, the creditors’ committee decided in favour of SKion’s offer.
SKion is confident in the company’s future and aims to continue and further expand the business both domestically and internationally. BMZ plays a key role within the value chain for energy storage systems. SKion intends to preserve the technologies available at BMZ as well as the extensive expertise of its employees in this field. Together with a newly established management team, SKion seeks to sustainably develop the company. The central objective is to retain as many employees as possible and to ensure the continuation of their employment with the company.
BMZ – Current Situation
The BMZ Group is a leading international manufacturer of lithium-ion battery systems. In October, BMZ Germany GmbH filed for insolvency under self-administration. The filing was triggered by a liquidity crisis and the need for restructuring, among other reasons due to the loss of a major customer in the Energy Storage Systems segment, as well as the resulting legal disputes and cost burdens. As a consequence, BMZ Holding GmbH was adversely affected and was also required to file for insolvency. The remaining companies within the group are operationally sound and were not affected by the insolvency proceeding.
Restructuring
The restructuring concept developed by BMZ management together with advisors provides for the carve-out of the operational business of BMZ Holding GmbH and BMZ Germany GmbH into a new structure. In the coming months, the focus will be on stabilising and expanding customer and supplier relationships as well as on further developing the organisation and integrating employees. The prompt establishment of the new structure also ensures the financial stability of the BMZ Group and enables a sustainable recapitalisation.
The realignment builds on the company’s technological core competencies and the capabilities of its employees, as well as on cost savings and growth initiatives – particularly in the area of battery systems for industrial applications and customised energy storage solutions. Demand for the core products is growing, and the market trend towards high-performance battery systems remains strong. The group has a solid order backlog internationally.
